About Gigajoule
One gigajoule is 1,000,000,000 J. Utility-scale and fuel-system reporting commonly use GJ.
About Therm
A therm is a large US customary energy unit for natural gas (≈ 105.5 MJ here).
How to convert gigajoules to therm
1 gigajoule is equal to 9.47817120313317 therm when both are expressed in joule-equivalents:
1 gj = (1,000,000,000 J ÷ 105,505,585.262 J) therm = 9.47817120313317 therm
Each gigajoule is defined as 1,000,000,000 J and each therm as 105,505,585.262 J in this tool, so one gj equals 1,000,000,000 ÷ 105,505,585.262 therm = 9.47817120313317 therm.
Let d(gj) be the numeric amount in Gigajoule (gj), and d(therm) the amount in Therm (therm). Then:
d(therm) = d(gj) × (1,000,000,000 / 105,505,585.262)
Equivalently, divide by how many gj fit into one therm (joules per therm divided by joules per gj):
d(therm) = d(gj) ÷ 0.105505585262
Or: therm = gigajoule ÷ 0.105505585262
Examples
Example #1: Convert 1 gj to therm
1 gj = 1 gj × (1,000,000,000/105,505,585.262) therm = 9.4781712031 therm
1 gj = 1 gj ÷ 0.105505585262 = 9.4781712031 therm
Example #2: Convert 10 gj to therm
10 gj = 10 gj × (1,000,000,000/105,505,585.262) therm = 94.7817120313 therm
10 gj = 10 gj ÷ 0.105505585262 = 94.7817120313 therm
Summary
To convert Gigajoule to Therm, multiply the value in gj by the ratio of joules per gj divided by joules per therm. Equivalently: value_therm = value_gj × (1000000000 / 105505585.262). Numerically, 1 gj equals 9.478171203133172 therm.
Relationship context
You are converting between SI energy (joules) (Gigajoules) and US / imperial engineering units (BTU, therm, ft·lb) (Therm). All values are mapped through joules first. The numeric factor is 9.478171e+0.
